My invention relates to a new and improved ventilator.

`One of the objects of my invention is to provide an improved ventilatorof the type which is connected to the bottom portion of the frame of awindow, so that when the window is opened at the bottom thereof, thecurrent of air will be upwardly deflected.

Anotherobjectofmy invention is to provide an improved ventilator whichcan be readily adjusted so that it can be installed in windows ofvarying width, without the use of skilled labor. d

Another object of my invention is to provide a ventilator of this typecomprising panes of glass which can be readily removed when it isdesired to clean them or to replace them.

Another object of my invention is to provide a ventilator of this typewhose angle with respect to the window frame can be readily adjusted.

YOther objects of my invention will be set forth in the followingdescription and drawings which` illustrate a preferred embodimentthereof, it being understood that the above genera-1 statement of theobjects of my invention is intended to generally explain the same andnot to limit it in any manner.

1929. Serial No. 371,022.

Fig. 12 is a sectional View on the line 12-12 of Fig. 11.

Fig. 13 is a top view of the bracket shown in Figs. 11 and 12.

The device shown in Figs. 1-4 comprises 55 a top outer telescopic memberl and a top inner telescopic member 2, which slide one within the other.It also comprises a bottom outer telescopic member la similar to l and abottom inner telescopic member 2a; similar to 2. o The members 1a and 2aare not as high as l and 2.

The height of the members 1 and 2 is sufficient to enable either oneofsheets of glass G and Ga to be raised and then tilted forwardly, asshown in dotted lines in Fig. 2, to enable either sheet of lass to bereadily removed. This is particularly desirable when it is desired toclean or to replace one or both of said sheets of glass.

The member 1 is provided with a depending end liange 3 and the member 1ais provided with an upwardly extending end flange 3a and the flanges 3and 3a telescope one within the other. Likewise, the member 2 75 isprovided with a depending end flange 4 and themember 2a is provided withan upwardly directed end flange 4a.

In the modified form of device shown in Figs. 5-7, the outer lowertelescopic mem- 30 ber 5 is rovided with an intermediate integral rig 6which slides within the rib 7 of the inner upper telescopic member 8.

Likewise, inthe form of devi-ce shown in Figs. 5-7, the outer uppertelescopic mem- 35 ber 5a and the inner lower telescopic member 8a haveribs of the type shown in Figs.

-6 and 7 In the device shown in Figs. 5-7 inthe ribs of the innertelescopic members serve as spacing ribs to prevent any contact betweenthe sheets of glass G and Ga. However, either one of the sheets G or Gacan be raised and then forwardly tilted to remove it from the device, asindicated in dotted lines in Fig. 2.

In the device shown in Figs. 1-4 inclusive, two sheets of glass G and Gaare slidably mounted between the inturned portions of the outertelescopic members 1 and 1a.

The sheets of glass G and Ga are of sucient length to permit them tooverlap at their adjacent ends. The sheets of glass G and Ga slidablycontact with each other in the device shown in Figs. 1-4, as this devicehas no spacing ribs. Hence, the free ends of the members 1, 2, 1a, and2a are pinched inwardly at the outer ends of the sheets of glass G andGa so as to minimize the possible tilting of the sheets of glass. Thatis, the members engage the sheets of glass at the non-overlappingportions thereof, so that the sheets of glass cannot rattle, and anair-tight device is provided.

In Fig. 8 the bracket for holding the frame is shown .as applied to thewindow construction W. The bracket consists of a metal strip 1() whichis secured to the side wallof the window 'frame in any suitable manner.A second bracket member 11 is adjustably secured to the first bracketmember 10 and the second bracket member is provided with a recess 12formed between two projecting ribs 14.

As shown in Fig. 8 for example, the inner rib 14 consists of an anglepiece which is connected by means of rivets 15 to the member 11.

The member 11 is provided with a slot which cooperates with a headed pin16 so that the member 11 can be adjusted with respect to the lixed strip10. The member 11 can be turned upon the headed pin 16 and it can alsobe moved up and down so that the bottom of the member 11 can always restupon the window sill. The bottom of the member 11 can also rest on thewindow sill underneath the lower sash, to prevent rain or wind fromentering.` For example, two positions of the movable bracket member 11are indicated in full lines and dotted lines in Fig. 8. Hence, theinclination of the movabie bracket member 11 can be readily adjustedthroughout a large range. The outer ends or1 the flanges 3, 4, and 3aand 4a enter the. recesses 12 and the frictional fit between the members1 and 2, and between members 1ct and 2a, is t-ight enough since saidmembers are made of resilient metal, to keep the parts in adjustedposition.

In the embodiment shown in Figs. 11-13, the fixed bracket member 17 isconnected to the frame of the window, as for example by screws 18. Theadjustable bracket member 1.9 is provided with a sl-ot 20, and it isprovided with ribs 21 to form a recess 22. The inner rib 21 is likewiseformed of an angle piece which is connected by rivets 23 or the like, tothe movable bracket member 19. The fixed bracket member 17 is providedwith a lip 20 which iits rictionally over the bracket member 19 so thatthe movable bracket member 19 can be adjustably held in any suitableposition. The portion of movable bracket member 19, which is above slot20, is laterally bent to frictionally bear against d the lip 20.

The movable bracket member 19 is connected to the xed bracket member 17by means of the pivot pin 24. The movable bracket member 19 is providedwith a lip 26 which acts as a stop.

In order to use the device, it is merely necessary to connect thebrackets to the sides of the window frame. The brackets can then beadjusted to any desired angle. The frame which is shown in Fig. 1 isthen longitudinally and vertically adjusted as desired and the frame isthen caused to enter the recesses of the brackets, namely, either therecesses 12 or the recesses 22.

Hence, it is clear that I have provided an adjustable device of greatsimplicity which can be manufactured at low cost, and which can bereadily applied by unskilled labor. It is also clear that the device canbe removed from one window and applied to another window of differentwidth, and that the sheets of glass can be readily removed for cleaningthem or replacing them.

Ihave shown the outer telescopic member 1 (in Fig. 3) provided withinturned lips for holding the inner telescopic member 2 in slidingengagement. However, I do not wish to be limited to this detail, becausesaid lips could be eliminated by causing the sidewalls of the telescopicmembers to converge, or by shaping the bases of said telescopic membersso that the inner telescopic members are slidably engaged within theouter member.

I have shown a preferred embodiment of my invent-ion, but it is clearthat numerous changes and omissions can be made without departing fromthe spirit of my invention.

I claim:

1. A ventilator comprising an upper frame and a lower frame adapted toslidably engage the adjacent ends of a sheet of glass between them, theheight of said sheet of glass being less than the distance between thesaid frames so that the said sheet of glass can be removed from the saidframe by raising it and tilting it, said frames extending over the topand bottom edges of said sheet of glass.

2. A ventilator having a frame comprising upper telescopic frame membersand lower telescopic frame members, a plurality of sheets of glassslidably mounted in'V said frame between said frame members, the heightof each said sheet of glass being less than the height of said frame sothat each said sheet of glass can be removed from the frame by a liftingand tilting movement, said frames extending over and slidabiy engagingthe top edges and the bottom edges of said sheets of glass.

3. A ventilator comprising a frame having an upper outer frame memberprovided with inwardly bent lips and a lower outer frame member alsoprovided with inwardly bent lips, said outer members having corre- 40said sidewalls, said ribs slidably engaging spending inner frame membersslidably located therein and held in position by said lips, and aplurality of sheets of glass slidably mounted between said lips, saidlips contacting with said sheets of glass to guide their slidingmovement, said lips comprising the sole means for guiding said sheets ofglass in their sliding movement, said frame members having substantiallyrectangular crosssections.

, 4. A ventilator comprising a frame having an upper outer frame memberprovided with inwardly bent lips and a lower outer frame member alsoprovided with inwardly bent lips, said outer members havingcorresponding inner frame members slidably located therein and held inposition by said lips, and a plurality of sheets of glass slidablymountd between said lips, said frame members having anges arranged intelescopic pairs, said lips contacting with said sheets of glass toguide their sliding movement, said lips comprising the sole means forguiding said sheets of glass in their sliding movement, said framemembers having substantially rectangular cross-sections.

5.V A ventilator comprising a pair of telescopic frame members adaptedto hold a pair of sheets of glass in overlapped and zo directlycontacting relationship, said frame members including means adapted tohold the non-overlapping portions of said sheets of glass from rattling,the to and bottom edges of said sheets of glass being held in directcontacting relationship.
